Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2009
Date Assessed: 2007-03-01
Assessor/s: Reis, R & Lima, F.
Reviewer/s: Collen, B., Darwall, W., Ram, M. & Smith, K. (SRLI Freshwater Fish Evaluation Workshop)
Justification:
Assessed as Least Concern due to its large distribution and no current major threat. Though this species is harvested, there is not at present any evidence that this poses a major threat to B. rousseauxii. Monitoring of this species should take place because of possible future threats acting on it.

Habitat and Ecology [top]

Habitat and Ecology: B. rousseauxii is a demersal (living at or near the bottom of the water body) species. Current evidence suggests a complex life cycle that includes the longest reproductive migration known for a freshwater fish species (Batista and Alves-Gomes 2006).
Systems: Freshwater

Threats [top]

Major Threat(s): Heavily fished for food but it does not seem to have a severe impact on this species. Also, a large dam is planned for Madera river which will cut through their migratory routes at Teonio waterfalls.

Conservation Actions [top]

Conservation Actions: There are no conservation measures in place and research into general biology and ecology (habitat status and population trends) are required.
